Abstract

Abstract: In order to study the safety reliability of mine dustproof water supply networks, factors affecting operation of the pipe networks were examined, thirteen evaluation indicators were identified, an evaluation indicator system was established, and the evaluation classification criteria were established. Based on the unascertainty measurement theory, an evaluation was built for mine dustproof water supply networks. Taking Fangezhuang coal mine as the object of application, the indicators were quantified and the measurement functions were constructed. The information entropy was used to determine the weights of the indicators. According to the identification criterion of confidence, the evaluation grade is Ⅱ, which shows that the network is safe and reliable. The model was applied to five typical coal mines taken as samples to evaluate, the safety reliability levels of their mine water supply networks. The evaluation results conform with the actual situation.

Key words: mine dust-proofing, water supply network, uncertainty measurement, information entropy, credible degree recognition, reliability evaluation
